plings, of which the following is a specification.

It is desirable in washing machines hav ing arotary cylinderoperating in a receptacle to be able to readily i'emovethe cylinder from the receptacle and in order that this may be done it isnecessary to provide 'a'drivi'ng means for the cylinder which will permit of such removal of the cylinderand yet will so engage the cylinder when it is operating as to drive it and hold it in place. 'With'the present detachable machine cou- 'pling this may be accomplished.

The'invention is illustrated in the accompanying drawings as follows':- I I I Fig. 1 shows a central section of the washer.' I L Fig.2 shows 'a section on the line 2-2 in Fig. 3 shows a section on the line'33 in Fig. 2. V i

' Fig. at shows a section on the line 44 in 1 marks the tub or receptacle, and 2 the cylinder, 3 an open bearing for the'frec end of the cylinder; This bearing is formed by a'simple loop, or angle iron. 'A stud 41 is secured by means of a plate 5 on the end of the cylinder and rests in the open bearing 3.

The drive shaft 6'is driven from any convenient source of power and operates in a bearing 7 arranged in the end of the tub 1. A driving arm 8' is locked on the shaft 6 by means of a key 9 and setoscrew 9 The arm is provided with the shoulders 11 and 12 and cam surfaces 13 and 13 .A plate 14 is secured to the end of the cylinder and is provided with the radially arranged ribs 15 which form a groove 16 adapted to receive the "arm 8. Aroller 17 is journaled on a pin 18-, the pin being secured to and between the ribs '15. A roller 19 is journaled on a pin 20. This pin is alsosecured between the ribs 15 and being offset in an axial direction from theroller' 17.

In order, to place'the cylinder in the tub the arm 8 is turned so as to bring the point .for cam surface 13 to the top. The cylinmachine.

der is then lowered into the tub hooking the I plete the engagement as the cylinder slides down by gravity on the arm 8, the roller 19 moving along the cam 13 swings thelower side of'the cylinder outwardly from thearm, thus tilting the cylinder as awho-le upwardly until the roller 19 drops under the Shoulder 12. This permits the cylinder to move down to alinement with the shaft 6 with the stud 1 in the; bearingB. In this position, it will be observed the cylinder is locked to rotate with the shaft GT-byieason of the engagement of the arm 8 with the walls of the groove 16. The shoulder 12 operating on theroller 19 prevents the disengagement of the cylinder when the shoulder isv in the upper position and the roller 17 resting onthe shoulder 11 prevents the dropping downof' the cylinder when'the roller 17 is in the upper position.

This is veryessential because the operators .ofthis type of device are not skilled and if itv were possible for the cylinder to lodge before reaching its final positionthe're wouldbe danger of breaking the What I claim as new is:
